According to CNN, Pilivarov, a Swiss physicist, plans to use a concentrated laser beam to influence the weather. This is an absolutely clean way because the whole process is free of any other chemical and artificial agents besides light and therefore does not pollute the earth's atmosphere. As the core material of laser, rare earth plays an important role.
Laser beam adjusts the weather
The report pointed out that the laser beam can mimic the process of cloud formation in nature, by concentrating the water vapor in the air, condensing into droplets and ice crystals. In this way, it will be able to make the air seemingly dry without water vapor into a cloud system. However, Pilivow said that the energy required to create a concentrated laser beam is equivalent to about 100 million watts of electricity produced by the entire nuclear power plant on Earth. Only such a large amount of energy can there be a solution to changing the moisture content in the air .
Pilivow pointed out that the technology is still in its infancy and can be used to regulate areas of the world where the weather is more intense, such as Chile, where droughts in California and floods occur. Through lasers, moisture can be transported to different locations, and Pilivow says the technology can help to reduce water vapor in flood-prone areas while increasing the water vapor generation in arid areas.
Condensate moisture control lightning
Laser in addition to condensing water vapor, but also control lightning. Pilivouv said the technology can stimulate the formation of lightning and control the discharge of water between the cloud filled system to trigger the rain. It is estimated that lightning incurs billions of dollars of losses each year, with thousands of people struck by lightning or even death. Therefore, when the size and area of the lightning generated are controlled, the lightning will be prevented from falling into a densely populated area and the loss of lightning strikes will be reduced.
The current laser-controlled weather experiment is still dominated by small, confined spaces, and Pilivow points out that because the control of the laser is filled with precision coefficients, how to safely use it to affect the weather without causing other injuries is a work in progress The direction of
Rare earth is the heart of the laser system
Rare earth materials are the heart of laser systems and the basis of laser technology. The development of optoelectronic technology by laser is widely used not only in the military but also in many fields of national economy such as optical communication, medical treatment, material processing (cutting, welding, punching, heat treatment, etc.), information storage, scientific research, testing and security Etc. have been widely used to form a new industry.
Laser and rare earth laser materials are born at the same time. So far, about 90% of the laser material is related to rare earths, solid state of the rare earth, liquid and gaseous have achieved stimulated emission. In the work of the laser material, rare earth has become a family of very important elements. This is related to its special electronic configuration, the multitude of available energy levels and spectral characteristics.
The technology used by Peelivo is also closely related to the more mature rare earth laser materials. If this technology is promoted, the losses to human beings from natural disasters such as heavy rain and lightning can be prevented in advance. The application of rare earth in this new field, once again enhance its value.
China's total reserves of various types of rare earth rank the world, but the application of rare earth technology needs to be improved. After the State Council integrates the rare earth industry, rare earth products and downstream applications will become the key breakthrough. The successful operation mode of rare metals in the Pan Asia Nonferrous Metals Exchange was also applied to commercial purchasing and storage of rare earth in October 2014, which complements the state purchasing and storage.
